Samsung SSD 850 EVO 32-Layer 3D V-NAND-Based SSD Tested
MojoKid writes Samsung just took the wraps off a new family of mainstream solid state drives, targeting the market segment previously occupied by its popular SSD 840 EVO series. The new Samsung SSD 850 EVO series is the follow-up to the company's current flagship SSD 850 PRO, but the new EVO is Samsung's first to pack 32layer 3D VNAND 3-bit MLC flash memory. The move to 32layer 3D VNAND 3-bit MLC flash brings pricing down to the .50 to .60 per GiB range, but doesn't adversely affect endurance because the cell structure doesn't suffer from the same inherent limitations of planar NAND, since the cells are stacked vertically with the 3D VNAND. The new 850 EVO drive performs well with large sequential transfers and also offered very low access times. The compressibility of the data being transferred across the Samsung SSD 850 EVO had no impact on performance and small file transfers at high queue depth were fast. Small file transfers with low queues depths, which is what you'd expect to see with most client workloads, were also very good. The Samsung SSD 850 EVO drives also put up excellent numbers in trace-based tests like PCMark 7.
>Sorry vendors. You can push your multi-terabyte hard drives all you want, but Moore's Law hasn't even remotely
>held true in the consumer space when it comes to storage demand.
Of course it has. I'm up to about 12TB in used storage, and I'm not anywhere near alone in this. Don't think that just because you're not using as much storage as computer users generally do now, that no one else is.
>The average consumer fills 10 - 20% of their drive capacity. Ever.
The average consumer isn't the market for hard drives. They don't even need computers since tablets and phones better suit the needs of non-technical people.
The sum total of all the special snowflakes like you who need many TB of storage pales in comparison to the Joe Schmoes who grab whatever drive is cheap and big enough. 1 TB has been "big enough" for 99.9% of people for a long time, and 1.5 and 2 TB drives only move when they're priced very close to the 1 TB versions.
Storage is fully commoditized. I bought my last hard disk drive at Costco, for shit's sake. I see them at supermarkets and drug stores.
People don't need more space to store HD video.
- They don't buy Blurays like they bought DVDs. They stream. And for the few times they do buy a Bluray, they don't rip it, they stream or download the heavily-compressed "digital" copy it comes with.
- They don't store their own HD video. They post to Youtube.
- The HD video they do store is stored in less space. Hardware accelerated H.264 encoding is ubiquitous.
People don't need more space to store music.
- Again, streaming.
- Music sizes have not increased as video sizes have with the introduction of HD. If anything, they've decreased.
People don't do shit else locally on their PCs that requires large amounts of storage. Even games with massive textures don't break the bank - 30 or 50 GB is nothing when you consider that people typically play a game, beat it, and then uninstall it. Only multiplayer-focused titles stay on the drive, and only a few at a time. 1 TB is enough to keep 20 of today's largest games installed at once. And gamers that do want (or believe they want) more storage represent the same niche that buys a $600 GPU (or two) every 8 months - they aren't the meat of the market by a long shot.
So good for you if you use 12 TB and want more, but 1 TB is enough for 99% of people, and 2 TB enough for 99.9%.
